Pumping at work

For those working, where are you pumping at work? I have an office, but it’s glass and the door doesn’t lock so there’s no privacy. And my job has me pumping in a supply closet, which I didn’t mind until people started trying to come in during my pumping sessions. They’d try to open the door and then knock when it wouldn’t open. Seriously frustrated with this process and now I’m afraid I’ll have to resort to pumping in my car.
